gene duplication
[/dʒiːn djuːplɪˈkeɪʃən/]
nounpl: gene duplications
duplicação gênica
1. A mutation event in which a segment of DNA containing a gene is copied, resulting in multiple copies of that gene within the genome
Gene duplication is a major mechanism of evolutionary innovation that allows organisms to evolve new functions.
A duplicação gênica é um mecanismo importante de inovação evolutiva que permite aos organismos evoluir novas funções.
2. The process by which genetic material is replicated, leading to the presence of redundant gene copies that can undergo divergence and acquire new roles
Through gene duplication, one copy of a gene can maintain its original function while the other copy mutates to perform a different role.
Por meio da duplicação gênica, uma cópia do gene pode manter sua função original enquanto a outra cópia sofre mutação para desempenhar um papel diferente.
Gene duplication is a fundamental concept in evolutionary biology and genetics studied in universities across Brazil, the United States, and Portugal. The term is used consistently in academic and scientific contexts with minimal regional variation. In Brazil, this concept is taught in biology courses at the undergraduate level and is essential for understanding concepts like human genetic disease and evolution.
